Application May 1, 1940, Serial No. 332,825

1 Claim.

Y The device forming the subject matter of this application is acultivator of the sled type, novel means being provided whereby thecultivating instrumentalities will adjust themselves automatically,transversely of the draft line, to provide for different spaces betweenrows. Another object of the invention is to provide novel means wherebyrelative vertical movement, yieldably resisted, may take place betweenthe frame portion of the machine and the sled portions thereof. Anotherobject of the invention is to provide novel means for adjusting thesoil-engaging elements relatively to the soil.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the presentinvention appertains.

With the above and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may

be made within the scope of what is claimed,

without departing from the spirit of the invention.

In the accompanying drawings:

Fig. 1 shows in top plan, a device constructed in accordance with theinvention;

Fig. 2 is a longitudinal section on the line 22 of Fig. 1;

Fig. 3 is a transverse section on the line 3-3 of Fig. 1.

The device forming the subject matter of this application may be made ofmetal throughout. It comprises pairs of parallel runners, extendedlengthwise of the draft line. Each pair of runners includes an innerrunner I and an outer runner 2. The runners I and 2 are rigidlyconnected by bridges 3, spaced apart longitudinally of the draft line.Substantially horizontal cultivators 4 are secured to the outer surfacesof the outer runners 2, and have an outward and rearward slant.Substantially horizontal cultivators 5 are secured to the inner surfacesof the inner runners I and have an inward and rearward slant. Thecultivators 5 overlap a little, across the median longitudinal plane ofthe machine, so that there is a full sweep outwardly, to the outer edgesof the cultivators 4. The bridges 3 are supplied intermediate their endswith upstanding posts 6.

The numeral 1 marks a main, hollow, transverse beam. On its uppersurface, the beam 1 has pairs of upstanding stops 8. The stops 8 aredisposed near the outer ends of the beam 1. A bracket 9 is secured ontop of the beam '1, midway between the extremities thereof. The bracket9 is provided intermediate its ends with a segment I0. The ends of thebracket 9 form upstanding inner stops II, cooperating with the stops 8in a way to be manifested hereinafter.

The main beam 1 passes through carriers I2 disposed lengthwise of thedraft line. The carriers I2 comprise parallel upper plates I4 and lowerplates l5, between which the main beam 1 is closely but slidablyreceived, the construction being such that the carriers I2 can havelimited movement transversely of the draft line and lengthwise of themain beam 1, between the stops 8-I I. The upper plates I4 and the lowerplates [5 of the carriers [2 are joined together, near their front andrear ends, by sleeves I6. The sleeves I6 are slidably mounted forvertical movement on the posts 6. There are removable abutments I! onthe upper ends of the posts 6. Compression springs I8 surround the posts6, between the abutments I1 and the upper plates I4 of the carriers I2.The construction is such that relative vertical movement is possiblebetween the beam 1 on the one hand, together with the carriers I2, andthe soil-engaging runners I and 2 on the other hand. The upper plates I4 and the lower plates I5 of the carriers I2 are connected by securingelments I9. The securing elements I9 are located closely enough to thebeam 1, on opposite sides of it, lengthwise of the draft line, so thatthe carriers I2 and the sleds comprising the runners I and 2, can haveno appreciable movement lengthwise of the draft line.

The numeral 2!] designates a hollow cross bar, located a little in frontof the sled structure comprising the runners I and 2. Intermediate itsends, the cross bar 2%] is connected to and supported by any appropriatetraction means 2I, such as the power-lifted draw bar shown in Patent1,939,950, issued on December 19, 1933, to Theophilus Brown. Rearwardlyextended arms 22 are secured to the bar 28, near the ends thereof. Therear ends of the arms 22 are connected to the end portions of the mainbeam I by chains 23. Depending anchors 24 are secured to the cross bar26, inwardly of the arms 22. The anchors 24 are connected to the forwardends of the sled runners I and 2 by Y-chains 25.

It is not necessary that the soil-engaging elements at the rear of thesleds be raised and lowered by hand, but they may be manipulated in thatway. Having that consideration in mind,

an angular hand lever 26 is fulcrumed at 21 on the segment Ill. Theupright part of the lever 26 has a latch mechanism 28 adapted tocooperate with the segment I D. The rearwardly extended part of thelever 26 is pivoted at 29 to downwardly diverging link 30. In the lowerends of the links 30, a horizontal hanger rod 3| is mounted. The upperends of suspension forks 32 are pivoted on the hanger rod 3|. The lowerends of the forks 32 are pivoted to the intermediate portions ofcultivator beams 33. The forward ends of the cultivator beams 33 arepivoted to the rear parts of the sled runners l and 2, as-

indicated at 34. The beams 33 carry soil-engaging elements 35, operatingbehind the sled runners l and 2.

Owing to the fact that the carriers I2, to which the sled runners I and2 ar connected; are mounted to move on the main beam 1, between thestops 8-H, transversely of the draft line, the soil-engaging elements,such as the parts 4, 5 and 35,- will work rea-dily betweendifferentlyspaced rows. Through the instrumentality of the-lever 2-6 and.associated parts, the soil-engaglng elements-35 can. beraised-andllowered at the -v will of an operator, in away which will-be.understood clearly when Fig. 2 of the drawings isnoted.

The runners l and 2, and-associated parts, will follow theirregularities in the ground, owing to theslidable relation between theposts 6 and the sleeves l6, and owing to the provision of the springsl8.

The specific structure hereinbefore described and delineated in thedrawings forms a simple but effective means whereby the broader featuresof the invention may be embodied in a satisfactory form.

What is claimed is:

In an agricultural implement of the class described, a main beam, meansfor supporting the beam, carriers including upper and lower membersbetween which the beam fits closely, securing elements connecting theupper and lower members to prevent movement of the carriers transverselyof the beam, the carriers being slidable longitudinally of the beam,stops on the beam and limiting the sliding movement of the carrierslongitudinally of the beam, sleds having vertical posts receivedslidably in the carriers and having their upper portions disposed abovethe upper members of the carriers, abutments on the posts, compressionsprings about the upper portions of the posts and interposed between theabutments and the upper members, soil-engaging elements assembled withthe sleds for vertical movement; and means carried by the beamforraising and lowering the soil-engaging elements at the will of anoperator.
